Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a weatherstrip door molding that is attached to the lower end of a vehicle door opening and has excellent friction and lubricity and durability as a water drainer.

[0002]

[Prior art]

 As shown in FIG. 4, the weatherstrip door moldings 70 are generally arranged on both sides of the window glass 9 of an automobile door and attached to the lower end of the door opening. Therefore, as shown in FIG. 5, the weatherstrip door molding 70 is composed of an outer door molding 7 arranged outside the window glass 9 and an inner door molding 8 arranged inside thereof. The outer door molding 7 includes a mounting body 71 and two upper and lower sealing lips 72 protruding from the mounting body 71 toward the window glass 9. The inner door molding 8 is also composed of a mounting body 81 and two upper and lower seal lips 82, like the outer door molding 7.

The seal lips 72 and 82 are composed of upper lips 721 and 821 and lower lips 722 and 822, as shown in FIG. Further, both are arranged on both sides of the window glass 9 so as to come into contact with the window glass 9 which moves up and down. Further, since the seal lips 72 and 82 are constantly in contact with the window glass 9, it is necessary to have elasticity and reduce frictional resistance thereof as much as possible. Therefore, some of the seal lips 72, 82 have a hair-implanted body 95 at a portion in contact with the window glass 9. The flocked body 95 is made of nylon pile. The mounting bodies 71, 81 are formed integrally with the body cored bar 5 made of stainless steel or the like, and are made of soft vinyl chloride resin, rubber or the like having rigidity.

[0004]

[Problems to be Solved] However, the above conventional technique has the following problems. That is, the flocked body 95 is made of a rigid nylon pile. Therefore, the flocked body 95 has a large frictional resistance with respect to the window glass 9. Therefore, when the window glass 9 is moved up and down, a large torque is generated on the seal lips 72, 82 having the flocked body 95. Therefore, the window glass 9 becomes difficult to open, and the durability of the weatherstrip / door molding 70 may deteriorate.

On the other hand, when the weatherstrip door molding 70 has no flocked body, the abrasion resistance is further increased. Therefore, when the window glass 9 is moved up and down, the torque applied to the seal lips 72 and 82 is further increased. In addition, since the flocked body 95 is not provided, sand easily enters between the seal lips 72, 82 and the window glass 9 and damages the window glass 9. Therefore, the durability of the weatherstrip door molding 70 may deteriorate. The present invention has been made in view of such conventional problems, and an object of the present invention is to provide a weatherstrip door molding excellent in friction lubricity and durability as a drainer.

[0006]

[Means for solving the problem]

 The present invention is a weatherstrip door molding that is provided on both sides of a window glass of an automobile and has a sealing lip that comes into contact with an ascending / descending window glass. The weatherstrip door molding is characterized in that the surface of the flocked body is coated with a low friction agent. What is most noteworthy in the present invention is that the surface of the flocked body is coated with a low friction agent. Examples of the low friction agent include silicone resin, urethane resin, and fluororesin (Teflon).

As the above-mentioned flocked body, there is, for example, a flocked by an electric flocking method in which a nylon pile is electrically charged and flocked. As a method of coating the above-mentioned flocked body with a low friction agent, there are, for example, brush coating, spray coating and dipping. The weatherstrip door molding includes, for example, an outer door molding and an inner door molding. The outer door molding and the inner door molding are composed of a mounting body and a sealing lip protruding from the mounting body toward the window glass. Then, the seal lip has, for example, an upper lip and a lower lip. The weather strip / door molding is made of, for example, vinyl chloride resin or rubber.

[0008]

[Action and effect]

 In the present invention, the surface of the flocked body is coated with a low friction agent. Therefore, the frictional resistance between the flocked body and the window glass becomes small when the window glass moves up and down (see Fig. 3). Therefore, little torque is generated on the seal lip when the window glass is moved up and down. Therefore, opening and closing the window glass becomes easy. Therefore, according to the present invention, it is possible to provide a weatherstrip / door molding having excellent friction lubricity and durability as a drainer.

【Example】

 A weather strip door molding according to an embodiment of the present invention will be described with reference to FIGS. As shown in FIG. 2, the weatherstrip door molding has seal lips 1 which are arranged on both sides of a window glass 9 of a door of an automobile and which come into contact with the window glass 9 which moves up and down. The seal lip 1 has a large number of flocked bodies 11 on its surface. As shown in FIG. 1, the flocked body 11 is coated with a low friction agent 111 on its surface.

Silicon resin is used as the low-friction agent 111. Then, as shown in FIG. 1, the low friction agent 111 is uniformly coated on the surface of the flocked body 11 by spray coating. The weatherstrip door molding is composed of an inner door molding and an outer door molding (see Fig. 5) like the conventional weatherstrip door molding. Further, as shown in FIG. 2, the outer door molding and the inner door molding are composed of a mounting body 10 and a seal lip 1 protruding from the mounting body 10 toward the window glass (see FIG. 5). The weather strip and door molding are made of vinyl chloride resin.

The seal lip 1 has an upper lip and a lower lip as in the conventional weatherstrip door molding (see FIG. 5). As shown in FIG. 2, the sealing lip 1 as the upper lip (see FIG. 2) and the lower lip is such that the portion of the flocked body 11 is constantly in contact with the window glass 9 when the window glass 9 is moved up and down. .. Therefore, the flocked body 11 is attached so as to generate frictional resistance each time the window glass 9 moves up and down. The flocked body 11 is made by charging a nylon pile to flock, and flocked the surface of the seal lip 1 by an electric flocking method.

As the nylon pile, one having a fiber diameter of 2 to 3 denier is used. As the nylon pile, a black one cut to a length of about 1 mm is used. Further, as shown in FIG. 2, the mounting body 10 is joined to a body core metal 5 (see FIG. 5) mounted at the lower end of the door opening. That is, the mounting body 10 is integrally molded and joined to the body core metal 5 during the extrusion molding. Others are the same as the conventional one.

Next, the function and effect will be described. In this example, as shown in FIG. 1, the low-friction agent 111 is coated on the surface of the flocked body 11. Therefore, as shown in FIGS. 1 to 3, when the window glass 9 is moved up and down, the frictional resistance between the flocked body 11 and the window glass 9 becomes small. Therefore, when the window glass 9 is moved up and down, almost no torque is generated on the seal lip 1. Therefore, opening / closing of the window glass 9 becomes easy. FIG. 3 is a graph showing the relationship between the coefficient of friction generated between the flocked body 11 and the window glass 9 and the load on the weather strip / door molding. The white dots in the figure show the weatherstrip door molding having the flocked body 11 coated with the low friction agent 111 made of a silicone resin according to this example. The black dots indicate a weather strip / door molding as a comparative example in which the conventional flocked body is not coated with a low friction agent.

As is known from FIG. 3, the weatherstrip door molding according to this example has an average friction coefficient of about 0.2. On the other hand, in the comparative example as the conventional flocked body, the average value is about 0.5. Therefore, according to this example, it can be seen that the coefficient of friction of the flocked body is reduced to about 2/5. Therefore, the frictional resistance when the window glass moves up and down decreases, and frictional lubrication can be easily opened and closed.

As a method of measuring the friction coefficient, a weather strip and a door molding (see FIG. 2) set on a jig are compressed at a compression load of 1.7 to 2.6 kg / 100 mm in a range of 1 Measure with a load of 0.7, 2.0, 2.3, 2.6 kg / 100 mm. At this time, the frictional resistance generated between the flocked body 11 and the window glass 9 in the weather strip / door molding is measured. Then, the coefficient of friction of the flocked body 11 with respect to the window glass 9 is calculated from this frictional resistance.
